Challenging imaging characteristics (low SNR, fast bi-exponential decay) have so far limited the application of 23Na-MRI in clinical environments. This work presents 3D Multi-Echo Radial Imaging of 23NA (3D-MERINA), a time-efficient acquisition protocol from which multiple parameter maps (sodium-density, T2*slow and T2*fast, free 23NA) can be derived in a single acquisition. Phantom and in-vivo measurements were analysed for the evaluation of parameter mapping and the inference of tissue characteristic based on decay behaviour. All parameters were acquired in a single sodium-density-weighted acquisition under relatively low SAR. Future investigation will exploit 3D-MERINA for SQF-SNR enhancement and the detection of MQF contrasts.
